[QUOTE="Tripodmvr7, post: 1999173, member: 115545"] Quick Load is not a wonder child that gives you accurate loads when you enter figures, but herewith the points where it does shine. 1. It can predict speeds from charges and the known parameters of the rifle to within say 50fps. This enables you to skip starting loads and use an intermediate load with safe pressures. From there you can calculate to within less than 20fps with the info gathered from shooting. Shooting confirms the calculated results and now you can give a better prediction of the nodes and see if that is true by shooting again. 2. Deciding on barrel length is easier if you know what speed you want to achieve and using QL. Although it predicts pressure this is not 100% accurate and erring on the safe side is advised. 3. Deciding on propellants is also easier as pressure and speed are supplied. It also gives case fill and amount of propellant burnt. 4. As a tool to analyze different components it is very good if sensible decisions are taken. Loading to max pressure is not my idea of a sound decision and I try to stay in the 50-55K psi range. 5. It saves on components and range time. I have gotten a friend of mine's 375 onto an accurate node with 8 shots. Good enough to go hunting. One day was taken up with this. GIGO is very true with QL and sound judgement is necessary. Actual shooting confirms your predictions. [/QUOTE]
